Ok if you don't know what Spore is I suggest you check out the following threads:

A character creator will soon be released for $9.99. There will also be a free demo as well which can be obtained from the official Spore website on June 27, 2008.

Apparently the demo will be a world wide release so you don't have to worry about your region getting screwed over. The retail version on the other hand, wont.

I'll be looking forward to the free demo, as for the retail copy, I think I'll pass for now and use that money towards the full game.

Isn't just on the PS3? If so blech.

No, aside from the PC it will also be on the Wii, Mac, and DS.

There's a possibility of a 360/PS3 version though. But no release dates for those consoles yet..
